David K. Lewis (Counterfactuals, Blackwell 1973) introduced a sphere semantics for counterfactual conditionals. He jokingly referred to the diagrams depicting such sphere models as Ptolemaic astronomy, hence the name of this package. It has nothing to do with Ptolemy or with astronomy, sorry.

The macros provided in this package aid in the construction of sphere model diagrams in the style of Lewis. The macros all make use of TikZ.
